摘要

针对水电工程中的地下洞室群围岩稳定问题，采用三维离散元软件3DEC

首先对围岩可能出现的破坏类型进行了分析，然后建立计算模型，对随机结构面进行了模拟，最后计算出了开挖过程中可能出现的破坏块体。使用的方法和得出的结论对类似工程具有一定的参考意义。

Abstract

The stability of surrounding rock mass of underground cavern is computed by using discrete element method software 3DEC. Firstly

the destroy type of rock mass is judged; secondly

the model is built and the random discontinuities are simulated; and at last the instability blocks are discovered after computation.The method and result can give reference to the similar engineering.
